Roof Drainage Under Paving Stone

Paving materials that incorporate small gaps allow water to seep through into quick draining gravel layers underneath.

Roof drainage under paving stone.

Non woven fabric allows drainage while preventing the sand from mixing with the soil. Lightweight panels spread the load and eliminate the need for a thick gravel base. Jointing and pointing for stone paving polymeric jointing mortars. 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.

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. 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. This can help avoid runoff and helps return water back to the soil instead of into a storm drain. Even if you move it off the patio and away from the house you may still have to move the water elsewhere.

Once all the parts of the drainage system were installed we covered the tubes with several inches of rock. Run the pipe under the pavers and out to an area that will handle the outflow. This system is designed for use over roof waterproofing membranes. Layers from top to bottom.

You can use permeable pavers for your entire driveway or just in areas that require better drainage. That line eventually emptied into the low spot in the back yard. 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. By using an elevated paver system water is channeled away from the roof surface reclaiming lost space.

This keeps the top surface dry eliminates runoff and lets water in the gravel layers gradually sink into the soil. A thin layer of screeded sand provides a level platform for the paver panels. Effectively draining water from a roof or plaza is a critical issue for every building. This indicates that a linear drain for the small project under consideration here.

Plaza and deck provides a thin lightweight weather and frost resistant installation for ceramic tile pavers brick or stone. An integral subsurface drainage component provides for elimination of infiltrated water.
