Can you lay Resin Bound Drives on concrete or tarmac?
Whilst the short answer to, can you lay resin bound drives on concrete or tarmac? is yes, it's worth considering drainage too. Even if you don't have either of these surfaces, reputable resin bound companies can lay the tarmac base surface over compacted ground. The surface or substrate you lay the resin bound drive, patio or pathway on depends on a few factors. Understandably, you'll likely want the water to drain away. Therefore, there are a few options to consider. Permeability, do you want a permeable or non-permeable driveway?
Permeable surface
If you want a permeable driveway that allows rainwater to drain through, you'll need a porous base. For example, like a crushed stone layer or a cellular concrete base. This helps prevent surface water runoff and flooding.
Non-permeable surfaces
If you don't need a permeable surface, you can use a non-porous base like existing concrete or tarmac. However, ensure they are in good condition and have proper fall for drainage to prevent water pooling. Firstly, existing concrete can be a suitable base if it's in good condition, level, and has proper drainage. A primer may be needed for new concrete. Secondly, existing tarmac can also be used if it's in good condition and has proper drainage. However, it's important to ensure it's level and free from cracks.
Laying a tarmac base over ground
A popular option is to install a resin bound driveway, patio or path over an existing concrete or tarmac base which has provision for drainage. Alternatively, if a suitable base or substrate is not available, a tarmac base can be installed and laid by a competent and professional resin bound company. Crucially, let's explore what your existing drainage needs to provide to prevent water pooling on a resin bound drive.
Existing drainage
Make sure your chosen substrate allows for proper drainage. Therefore, check if the existing ground or sub-base has adequate drainage provisions like channels or soakaways. Crucially, SUDS compliance is needed if you live in an area with regulations on Sustainable Urban Drainage Systems (SUDS). Therefore, you may need a permeable base to comply with local requirements. Fortunately, all our resin bound surfaces are SUDS compliant.
Final Thoughts
Always consult with a qualified resin bound driveway installer to determine the best substrate for your specific needs and site conditions. They can assess your existing ground, drainage and local regulations to recommend the most suitable option. Therefore, by considering these factors and seeking professional advice, you can ensure your resin bound driveway has a strong and stable foundation that is long-lasting and functional. Crucially, the substrate will ensure your resin bound surface remains stunning for longer whilst allowing water to drain away.
