BIO BLOKS 80 & 150 FOR DRAINAGE & WATER FILTRATION (FOR PONDS) 1 A. BIO BLOK DRYWELL – Bio Blok 80 HDG & Bio Blok 80 HD-GF Reinforced. Improving Golf Course and Field Drainage. This system can solve the problem of bunker flooding following heavy rain and is substantially more efficient than traditional stone drywells. Each 54cm x 54cm x 55cm Blok can hold 152 litres of water (a porosity of 95%) by comparison a stone drywell has a porosity of 20%. More efficient and an economic solution via reduced excavation and stone requirement Long service life of 100% polyethylene Bloks Full engineering advice available to assist in dimensioning project Bloks are easily cut to enable an increase in lateral surface area & porosity Standard Size: Bio Blok 80 HDG 54cm x 54cm x 55cm Extra Strong Reinforced Bio Blok 80 HD-GF 54cm x 54cm x 55cm. For use were vehicular traffic is expected. 1 B. RAIN & STORMWATER SYSTEM For Soakaways & other landscaping projects Widely used in Continental Europe Excellent as Golf course / bunker drainage Saves approx. 80% of excavation cost for soakaways and preserves ground water resources A single Bio Blok unit can contain 144 litres of water as each Bio Blok has a far higher void percentage than traditional soakaway and stone drainage system A Geo textile fibre cloth is needed to prevent sand or soil from filling the Bio Blok unit – one 180cm x 250cm sheet will cover two bloks at £8.50 per sheet, 4 blocks: 290 x 260cm £14.0050m2 of roof area normally requires two Bio Bloks for average UK rainfall areas 2. WATER FILTRATION OF PONDS: Bio Blok 150, 55cm x 55cm x 55cm. For the reduction, separation and decomposition of organic material, together with ammonia reduction. Outer tube diameter 55mm. Void = 88%, area of flow 64%. Other types of Bio Blok are used for water purification via trickling filters and in waste water treatment. please ask.
