B&G Offers Expert Flood Control Engineering In Cebu

BrownN'Greenfield's GeoB&G Geotextile Tubes and Bags are the perfect solution to flood control and alleviation. 

For flood control on rivers or coastal, Geotextile Tubes are filled with sand or silt and form a large impermeable barrier - taking up shape much like giant sandbags. They can be quickly filled using a river or ocean-going dredger (Enviro-Dredging), stand-alone or pontoon-mounted slurry pump, or filled mechanically using standard backhoe equipment. 

During filling, the pumped sand remains inside the Geotextile Tube and the water decants-out clean and clear; leaving a solid, consolidated structure for very efficient and effective flood control. The water returns to the river or ocean quickly.

B&G offer the full service, from design to supply and installation. We can offer advice on sizes and methods of filling, capacities, final fill height, and comparative costings.

We also advise on appropriate scour aprons for the flood defense system and any backside erosion control or geohazard protection, if necessary. 

Our GeoB&G Textile Tubes are manufactured using ISO-Certified and CE-Mark high tenacity woven and knitted polyester (PET) or polypropylene (PP) and can achieve heights of up to 3.5m and lengths of up to 100m. They include handling straps and fill ports (chimneys) and are delivered concertina-folded on pallets or rolled-up onto a steel inner corps for ease of handling and deployment.

For flood defense and flood alleviation, one big bonus is that geomaterials (clay, silt, sand, and gravel) from nearby rivers can be used to fill the GEOB&G Tubes, and therefore increase the flood capacity and improve the hydraulic radius of the river at the same time.

With our geotechnical expertise, guidance and training, 100-200 running meters of GEOB&G Tubes can be constructed in one day.

BrownN'Greenfields Geotextile Tubes have a 120 year design life, as required by highways agencies world-wide and can be used in conjunction with rock armor or grout-filled mattresses protection for very harsh environments.

B&G's tubes and bags can be stacked on top of each other to form a robust and higher defense barrier. Typically they can be stacked up to seven tubes high, or higher, if there is additional geotechnical reinforcement.
