## Description

RainCatcher Graf Rain Bloc 300 Litre Storm Crate Drainage anti-flooding storm crates for rapid drainage of land. Surface water is diverted or soaks down into crates and from there dissipates into the lower ground clearing water quickly from the surface. HGV load quality and used for drives, carparks, pitches, lawns and areas prone to localised flooding. Drainage anti-flooding blocks or Graf Flood Attenuation Bloc with 300 litre capacity (95% void) for rapid drainage of land. Surface water is diverted or soaks down into weight resistant crates and from there dissipates slowly into the lower ground clearing water quickly from the surface. This product is HGV load quality and can be used for drives, car parks, pitches, lawns and areas prone to localised flooding. The rigid crates are made in black polypropylene with dimensions 1200mm (l) x 600mm (w) x 420mm(h) and will hold a maximum capacity of 300 litres gross or a working volume of 285 litres. To build the attenuation system, the blocks are connected together to achieve required capacity and design. The crates are wrapped in a non woven permeable geo-textile to slow the drainage of the rain water forming in effect a high capacity, simple and trouble free soakaway system. Where storage and reuse of the water is preferred, the block system can be wrapped in a water-proof membrane forming a large underground tank that can be pumped for other use. Alternative grades of Geo-textile and other membranes are available on request, however for the purpose of this listing you will be supplied with 100 gsm grade, approx. 2.25 sqm per crate

Review: A very good quality soakaway crate - Arrived pre-assumbed and sturdy - I took a risk ordering this with no reviews and the seller (Eco Trade Counter) with only a couple of reviews in the last 3 months but this one paid off. I placed the order quite late in the day, during postal strikes at Christmas time but somehow had a phone call the next day with the delivery driver outside my house! The soak away crate arrived pre-assembled, it was very strong and sturdy with enough geotextile terram to cover the top and sides. It was easy to snip the plastic around the cut out areas for the pipe - the product made the job much easier that it could have been. Highly recommended!
Review: Sturdy soakaway with sufficient geotextile membrane. - Excellent - arrived in good condition with sufficient Geotextile membrane. The description on desertcart is not clear with regard to the membrane as it lists 2.25sqm, which wouldn't be enough to cover this crate. However, it should read 2.25 metres square, so you get just over 5sqm, which is plenty to cover the crate. The crate is really sturdy and has multiple pipe entry points.

### ⭐⭐⭐⭐⭐ A very good quality soakaway crate - Arrived pre-assumbed and sturdy

I took a risk ordering this with no reviews and the seller (Eco Trade Counter) with only a couple of reviews in the last 3 months but this one paid off. I placed the order quite late in the day, during postal strikes at Christmas time but somehow had a phone call the next day with the delivery driver outside my house!

### ⭐⭐⭐⭐⭐ Sturdy soakaway with sufficient geotextile membrane.
*by M***K on 9 October 2025*

Excellent - arrived in good condition with sufficient Geotextile membrane. The description on Amazon is not clear with regard to the membrane as it lists 2.25sqm, which wouldn't be enough to cover this crate. However, it should read 2.25 metres square, so you get just over 5sqm, which is plenty to cover the crate. The crate is really sturdy and has multiple pipe entry points.

### ⭐⭐⭐⭐ Good, well built crate but membrane supplied was not big enough to cover crate.
*by M***. on 26 August 2024*

This is a well built crate, that does the job. The one down side was that the membrane that was supplied with the crate was not big enough to cover the crate. Luckily I had some other membrane that I could use to cover the gap.
