1.0 Cubic Metre Soakaway Crate Set – Includes Geotextile and Tape!

Order a Soakaway Crate Set (1.0 Cubic Metre) Online – Easy Cost Effective Solution.

This set is comprised of:

• 8x   Geocell Soakaway Crates (40 Tonne Load Capacity – total of 1m3)
• 1x   Waterproof Textile Jointing Tape (50m Roll)
• 1x   4.5m x 3m Geotextile (100gsm)

That’s enough crates, geotextile and tape for a 1m3 soakaway!

How it works – Geocell Soakaway Crates:

Stormwater enters the plastic soakaway crates attenuation tank through the input manhole, which incorporates a silt collection sump along with a galvanised leaf set basket. Water passes through the tank and exits through the outlet manhole, which includes an AquaBrake flow controller apparatus. This flow control apparatus modulates the release speed of water in the tank, and in so doing, enables the tank to fill. As a result of water entering the tank at a higher rate than it could depart, the void space then fills with water. The Inlet/Outlet pipe will function as a flushing channel. This perforated pipe is wrapped entirely in High Flow Filtering Geotextile, which prevents silt entering the block region. As the tank continues to empty at a pre-determined pace, air re-enters the tank through the same air port system. The roof of the finished tank has to be lower than the cheapest gully trap onsite.

Soakaway:

The soakaway is normally best constructed as a long narrow structure. The inlet pipe comes in at roof level and faces downwards so the water can percolate into the tank. The blocks are wrapped in Geotextile, to protect them and to keep clay from filling up the empty space. An air vent pipe is installed on the maximum height point with a cowl at the top or it can be vented back into an inlet manhole. There’s no outlet from a soakaway, therefore no flow control unit is required.

Benefits:

● 100% sealed tank
● Full installation service provided
● 12 years experience as market leader
● Quick installation – reduce site access delays
● Increased land usage – tanks are sub surface
● Economical – generally more cost efficient than any other equivalent sealed tank
● Cost effective – reduced costs for excavation and disposal of material
● Modular – easy to create any shape
● Strong – designed to support shear loading
● Lightweight – no cranes required
● Determinate volume – one cubic metre of matrix tank modules contain 950 litres of water, whereas stone fill will only provide 300 litres of storage per cubic metre.

Design Criteria:

The soakaway attenuation tank is assembled using matrix module blocks. These blocks can take passing loads of up to 40 tonnes/m2. The void ratio of every block is 95%. The soakkaway crates are made from polypropylene. The tank is sealed with a layer of geotextile membrane, which is completely welded together to make a 100 percent seal. All pipe penetrations should be fully sealed into the geotextile membrane. The membrane is shielded by a layer of heavy duty protection geotextile, to prevent damage from construction or backfilling. A range of air extraction vents/flushing points are then placed in the roof of the tank.

Note:

It’s crucial that the underground tanks are totally sealed, otherwise soil water and silt particles can enter the void space and consume capacity. Preferably, the bottom of the tank must be 500mm above the ground water level. Otherwise floor water relief measures must be put into place.

BIG BRANDS, SMALL PRICES.

After being let down by another online supplier I decided to give Easymerchant a try based on a recommendation from a friend. I've placed several orders for twinwall drainage over the past few weeks and they have not let me down once. They always answer the phone and happy to answer any questions. Highly recommend!
