If block paving is not installed correctly, it will most definitely sink and spread. Therefore all of our block paved drives, paths and patios are laid and installed to the highest standards. We use MOT Type 1 stone to all sub-bases, full haunch boards to stop any movement and sinking, and all of the blocks we use are sourced from the proven suppliers. Our excavation for block paving will always be carried out to guarantee at least 6 inches of new base foundation. Abel Driveways LTD will always set the outside border of the block paving in cement to prevent it from spreading out with new edging kerbs behind it to reinforce the paving if required.
