Looking for the best roof rainwater management system that you can buy online? Here are some advices to pick the best stormwater retention management system. Nowadays, you can use soakaway crates to make a soakaway system. In this case, you have to wrap them in a permeable geotextile that allows the water to leak out into surrounding earth at a rate that is accepted by the ground. As a result of this, the ground can cope with all the rain water and surface without causing floors or creating stagnant water.
A soakaway provides a Sustainable Urban Drainage System (SUDS) which complies with this regulation. See more in Building regulations below. When you have drained the water from the ground you will need to direct it somewhere. It should be directed into the rainwater or storm drain system of the mains drains or into a soakaway, but never into a foul water system. You should not direct rain water into a cess pit or septic tank either (see our project on Foul and Surface Water Drainage Systems for more information).
While we recommend your ground-worker conducts a soil percolation test and creates a set of calculations, there is an alternative method that will give you a rough idea of the soakaway size you’ll need: If your soil type is not too heavy/clay, you can assume that one crate (1000mm L x 500mm W x 400mm H) will be sufficient for ten sq metres of driveway or roof covering etc. Five crates are equal to 1 cubic metre, and one cubic metre is suitable for 50 square metres of surface area. So get your tape measure out and calculate the total surface area in square metres.
Stable Design: Interlocks vertically and horizontally for maximum stability, avoid the whole system from floating. Fast Installation: The built-in socket and ports bring extremely convenience of quick installation. High Void Ratio: 96% void ratio providing greater water storage capacity with reduced excavation and disposal costs. High Compression Load: Resisting stretch and extrusion by fully utilizing triangle’s stability and round shape. Unique Columnar Construction: Adopt cylinder-shaped construction, suitable for non-trafficked, trafficked or heavily trafficked application. Structural integration: Distributing the loaded weight on to all the plates, fully utilized the effect of each plate. Read extra details on Multi Functional Water Management System.
