Roof drainage under paving stone.

Tile tech pavers provide durability protection and performance for the roof system from harsh weather conditions while providing drainage and a level walking surface and can be used on tpo roofing and epdm roofing systems. Layers from top to bottom. The top layer will be the pavers of your choice. This system is designed for use over roof waterproofing membranes.

Permeable pavers allow rainwater to filter through or between the stones to return to the soil. You can use permeable pavers for your entire driveway or just in areas that require better drainage. This indicates that a linear drain for the small project under consideration here. This can help avoid runoff and helps return water back to the soil instead of into a storm drain.

That line eventually emptied into the low spot in the back yard. Effectively draining water from a roof or plaza is a critical issue for every building. This keeps the top surface dry eliminates runoff and lets water in the gravel layers gradually sink into the soil. Once all the parts of the drainage system were installed we covered the tubes with several inches of rock.

Paving materials that incorporate small gaps allow water to seep through into quick draining gravel layers underneath. Lightweight panels spread the load and eliminate the need for a thick gravel base. Even if you move it off the patio and away from the house you may still have to move the water elsewhere. Plaza and deck system eliminates the dead load problems 50 lbs ft2 245 kg m2 and high haulage placement costs associated with conventional gravel drain beds.

A thin layer of screeded sand provides a level platform for the paver panels. From 50mm deep units for roof drainage to 250mm deep motorway drains and in a ever widening range of materials including polymer concrete wet press concrete hdpe and stainless steel. Do not drain your water directly into a storm drain or ditch as this water can be full of contaminants that will end up directly in your local streams and lakes. Run the pipe under the pavers and out to an area that will handle the outflow.

Plaza and deck provides a thin lightweight weather and frost resistant installation for ceramic tile pavers brick or stone. Where the tube passes by the downspout from the gutter we installed a y fitting and drained the roof water from the gutter system directly into the main drainage line.
