Common Paving Mistakes Homeowners Should Avoid

While selecting an attractive material is an important part of the process of successfully paving a new paved driveway, pathway or outdoor area, it is not the only part. Poor site preparation, weak foundations, drainage issues and/or inadequate compaction can lead to problems like cracking, water pooling and sinking. When it comes to paving, homeowners need to take into account what their property requires, and be mindful of the experience of the paving contractors Melbourne, who will be able to ensure that the materials used, their preparation and installation methods are appropriate to the project to ensure a durable, long-lasting result.

Let's take a look at some of the things not to do when you're planning to get a residential paving project.

1.   Failure to prepare the site properly.

Visible paving is just one of the components of the completed surface. Beneath it, there is a foundation that must be able to withstand the stresses of the property and the stresses it is subjected to.

The ground should be evaluated prior to the paving installation. This may require vegetation clearing, removal of organic matter, removal of poor soil or existing materials and correct levels.

The importance of this is related to the fact that movement of the ground beneath pavement can occur.

For instance, if there is soft or poorly compacted material under a driveway, the repeated load of vehicles may lead to time-and-place settlement of the surface above. The pavement may not have been faulty; it could have begun with the foundation.

What factors should be taken into account when preparing the site?

An appropriate preparation can include:

·       Identify the current state of the ground at the site.

·       Removing unsuitable material

·       To design and construct a trench of the required depth.

·       Establishing appropriate falls

·       Preparing the subgrade

·       Pouring the base material for the structure.

·       Compacting foundation materials

·       Preplanning drainage prior to installation of finished surface

Exactly how to do it should be site specific and not based on any formula.

The requirements for a pedestrian path, residential driveway, and an area where heavier vehicles are used do not necessarily have to be the same.

Homeowner tip: When considering a paving estimate, be sure to not only consider the type of material that will be exposed after paving is completed. Imagine what is going on under it.

2.   Using an Inadequate Sub-Base

Under many paved surfaces is a sub-base that is an important component of the structure. It aids in load distribution and offers a level surface for the paving system on top of it.

Inadequate base can lead to greater risk of settlement and movement.

This is especially relevant for driveways where vehicles are driven over on a regular basis. If a foundation is working well under a lightly trafficked road, it might not be suitable for a road with frequent traffic.

What happens if the root is not sound?

Owning a home often brings certain changes that are noticed by their homeowners eventually:

•                    Low spots

•                    Uneven paving

•                    Cracks

•                    Loose pavers

•                    Depressions

•                    Remember to move around crowded areas.

•                    Recurring repairs

The ideal depth does not exist for all properties and so the appropriate foundation is not one depth, but rather depends on the individual property. These should all be taken into account when deciding on soil conditions, drainage, type of paving and anticipated loads and site usage.

That's why homeowners need to be careful about the generalities of “all paving projects are the same and call for the same foundation construction.”

3.   Not considering drainage and water runoff.

One of the most significant factors to consider with outdoor paving is water.

Rain has to have a place to go. Where a paved area is unsuitable for levels and/or drainage, water may accumulate on the surface or impact the materials below the surface.

Ongoing water issues can lead to erosion, deterioration and instability.

The following are typical drainage issues:

•                    Areas that collect water after a rainstorm.

•                    The flow of water towards buildings

•                    Blocked drainage points

•                    This is caused by inadequate planning of surface falls.

•                    Weakening of edges of paving due to erosion.

•                    Water collecting in low areas

•                    The material beneath the surface is becoming saturated.

For any paving project, therefore, it is important to take into account the current drainage situation on the property.

Examples of elements that can affect water flow across a property include downpipes, garden beds, Kerns, stormwater infrastructure and surrounding ground levels.

4.   Using only appearance to select paving materials.

An ideal paving material for a showroom may not be appropriate for a specific project.

It is important for home-owners to think about what they are looking to do in the area.

There are many different needs for a driveway, garden path and patio.

To select a paving stone material, keep in mind:

•            Expected traffic

•            Vehicle loads

•            Pedestrian use

•            Surface durability

•            Maintenance

•            Slip resistance

•            Appearance

•            Budget

•            Weather exposure

•            Surrounding landscape

The ease with which future repairs can be made.

These can be different characteristics of concrete, concrete pavers, brick and natural stones.

The best option will be determined by the project.

For driveways

Durability, appropriate load bearing performance, drainage, correct installation should be the priority, in general.

For pathways

These could be safety, accessibility, surface qualities and maintenance.

For patios

While appearance and integration into the landscape may be more important to homeowners, drainage and durability remain important factors.

The error is not selecting a specific material.

The error is sticking to any material without taking into account the conditions it will be used in.

5.   Not Minimizing the Foundation's moisture content

One of those parts in paving that homeowners may not notice but could have a profound impact on the overall job is compaction.

It is important to compact the foundation materials appropriately to ensure a stable layer of material is formed to support the material above.

If it is not compacted well the material may settle after installation.

This can lead to an apparently successful paving job which causes unevenness several months or years after installation.

Signs of Foundation Movement

Watch for:

•            Depressions

•            Uneven sections

•            Rocks that roll when walked on

•            Cracks

Water is likely to collect in low areas.

Settlement in the same location, over and over again.

The method of compaction selected will depend on the material, the construction of the layer and the site conditions.

Another reason homeowners should not allow their choice of contractor to be made based on how fast the paving is done is because of this.

6.   Making Use of Edges, Joints and Movement

People who live at home tend to pay attention to the center of a paved area because the majority of the surface is visible.

But it's not just the edges and joints that should be considered.

For segmental pavers, the right edge restraints can help restrict lateral movement. Individual units will slowly move with repeated use if not properly restrained.

Problems can include:

•                    Gaps between pavers

•                    You can move at the edges.

•                    The loss of the jointing material.

•                    Weed growth

•                    Uneven patterns

•                    Deteriorated edges

Imagine a line of objects that are placed side by side with no object blocking their side-to-side movement. Individual pieces can tend to separate overtime.

A similar problem can occur for paving if the perimeter is not sufficiently restrained.

This doesn't imply that each paving system has exactly the same edge and joint solution. How to do it appropriately would depend on the system to install and the material.

Homeowner tip: Prior to project begin, ask your contractor how the edges will be restrained and how the joints will be finished.

How a Good Paving Assessment Should Begin

The property needs to be viewed before installation as a whole site and not as a paving site.

There are some questions to be answered.

What type of material lies beneath the surface?

Preparation can be impacted by existing paving, concrete, soil, vegetation and previous paving repairs.

What will be done with the area?

The needs of a driveway that receives daily traffic as opposed to a decorative walkway are quite different.

What happens to the rain water?

Existing levels and drainage facilities should be taken into account before final levels are set.

Is the base solid or firm?

If the ground is soft and/or unsuitable for the type of work, further preparation may be necessary.

Which material is appropriate for the use?

The choice of the material should be made based on performance and appearance.

This type of evaluation is more helpful than picking a paving product and seeing what the site can do for it.

Before hiring a paving contractor, it's crucial to ask these 8 questions.

Homeowners don't have to be paving experts to engage in a successful dialogue with a contractor.

Ask:

1.      What are the requirements to prepare my site for it?

2.      What will have to be taken off when installed?

3.      What type of foundation or sub-base do you plan to use?

4.      What method(s) will be used to compact the foundation?

5.      What is the drainage of the surface after it is complete?

6.      Why this type of paving material is the best choice for my application?

7.      What exactly is included in the quotation?

8.      What kind of warranty/terms of workmanship are available?

Reliable, honest answers to these questions can often provide more information about a proposed project than just the price.

Professional Paving Advice Is Particularly Valuable.

A professional assessment is particularly helpful in the following circumstances:

•            A large driveway

•            Wet, rocky, and/or uneven ground

•            Significant excavation

•            Existing drainage problems

•            Steep slopes

•            Heavy vehicle use

•            Existing settlement

•            Complex surface levels

•            Large outdoor areas

•            Previous paving failures

That doesn't mean homeowners should always hire outside companies for all the small paving tasks that need to be done.

The more complex the site, the more important it becomes to assess the site appropriately.

After installation, there are steps homeowners can take to protect their paving surfaces.

All well-installed paving requires regular maintenance.

Homeowners should periodically:

•                    Check drainage points

•                    Remove weeds

•                    Remove build-up of dirt and organic matter

•                    Watch for migration or displacement of birds

•                    Monitor joints

•                    Address standing water

•                    Fix minor issues before they become serious.

•                    Be extra vigilant post major rainfall.

When water once used to run off starts to be puddled in one place, it's a change worth looking into, not a change that should be ignored.

Frequently Asked Questions

•                    What is the worst homeowner's mistake when it comes to paving?

The biggest mistake is to consider the visible paving work as the project itself. Using good material can result in poor surfaces when poor ground preparation or poor foundation construction or drainage problems occur.

•                    Why is it that paving sinks?

There can be multiple reasons that the ground sinks, such as insufficient preparation, poor compaction, insufficient foundation support, and/or drainage problems. The cause must be evaluated not assumed.

•                    Should there be drainage in paving?

A key factor in outdoor paving is water management. Proper surface elevations and drainage may be necessary to keep water from pooling in areas that will cause damage to the pavement or to the property.

•                    Does a thicker paving base mean it is more durable?

Not necessarily. The soil and drainage conditions of the site, the system of paving and the anticipated loads should be considered and reflected in the foundation requirements. Just putting material on is not enough to fix a structural issue.

•                    If homeowners receive multiple paving estimates, what should they do?

Multiple quotes can be helpful when comparing them as long as homeowners compare the work done, not the price of the job.

•                    What are some reliable signs that a paving company is reliable?

Check for clear communication, there is a detailed written scope, they have experience in the field, appropriate recommendations for the site, pricing is transparent and warranty/workmanship terms are clearly defined. Some of the finished examples of similar work can also be of great assistance to homeowners in the assessment of a contractor.

Conclusion

A good paving is not just made with good material.

It's the culmination of a series of decisions, from site assessment and water management to foundation preparation, picking materials and installing them properly.

If you avoid the seven mistakes described here, you will save yourself a lot of problems that could otherwise become a burden in maintaining a potential improvement.

When you're thinking about paving you shouldn't ask yourself "What is the least expensive way of paving this area?".

Start with:

What is required on this site in order for it to function properly, what is proposed, what is part of the work that is being done?

That change in mind-set may help you compare contractors more intelligently, choose the materials you need more wisely, and prevent issues that might not arise in the paving until it is installed.

A well-built paving project doesn't just have to look good on its final day. It should be engineered and built to accommodate the property's existing conditions, drainage, and intended use and long-term performance.
