A smaller stone (aggregate) won’t allow surface water to drain as easily as a larger stone. Therefore, only use a smaller stone if drainage to bedding or drainage system is in place.
We consider a ‘full resin bound installation’ from start to finish is always the best way to go. This means full preparation of substrate, new sub base (possibly with grid system) and resin installation with appropriate aggregate. However, as mentioned above we know that budget is an important consideration for most of us. If you opt for an overlay of an existing concrete surface or tarmacadam surface, it’s very important to ensure any cracks are completely filled (by this we mean small cracks) otherwise there’s a bigger chance of paving surface failure in the future.
