Percoa is pre-cast which makes it easy to install, immediately useable, and cost effective.  Slabs are precast and cured in a controlled environment allowing for a delivery of 85% of their total compressive strength with a high flow rate. This makes them immediately usable. They are pre-cast and can be placed year round, in almost any type of temperature and weather conditions.

Can be installed any time of year in almost any type of weather
