ProductBesTec™ Chamber Rock Mattress (a.k.a. BesTec™ KDW) are rock- filled mats of extremely tear resistant netting. They are flexible (i.e. forgiving of grading mistakes), yet strong and easy to use. BesTec™ KDW are construction elements used for various stabilization techniques ranging from aquatic to upland applications. UtilityBesTec™ KDW comes in prefabricated standard or custom sizes upon request (for bigger quantities), the production will be done to the place of installation. They are ready for installation upon delivery. Installations require less site preparation then conventional methods and are far more time efficient. The interior design guarantees extreme flexibility, allowing for 180 degree bends while simultaneously maintaining their true shape. BesTec™ KDW conform to existing ground conditions without subsidence of individual stones, even if ground changes after completion of the project. Materials used in the manufacture of BesTec™ KDW are chemically inert, non- corroding, high tensile strength sythetics and rock. A large volume of internal voids allows for high water permeability. Filter fabrics can be incorporated upon request. Retrofit with vegetation is possible, site conditions permitting, the vegetation-carrier Composit™ is recommended. A special type prepared for plants for higher hydraulic and mechanical conditions is available. For further details please see BesTec™ vegetated Rip Rap, type VDW and Composit™ .
QualityBesTec™ KDW have been inspected prior to delivery and individually tested with the test certificate according EN-standard assuring our customers that stringent material and quality requirements have been met. The filling BesTec™ KDW are custom filled with locally available rock ranging in size from 50-150mm / 2-6'' inches. Due to its internal architecture and exterior interconnectedness The nettingBesTec™ KDW casing is an environmentally inert PP netting, which is resistant to damage by light, frost, salt, and chemicals. Our special netting has been woven in one piece. It is a special netting, without the typical weak spots. Our netting is strong enough to allow BesTec™ KDW to be handled by power equipment.
Number of compartments:as parallel configuration: as perpendicular configuration (for steper slopes/applications): Installation Different applications require different installation procedures. All require the use of heavy equipment capable of handling a minimum of 5 tons (approx. 0,4-0,5 to/m²) of weight when fully extended. Generally grading will be part of site preparation. However certain applications, such as underwater placement, often proceed onto existing ground. Spreader bars especially designed for this product are available for lease or purchase. Equipment differs for installation on dry land or submerged below water. BesTec™ KDW rely on their significant weight for stability. After placement individual modules must be tied together manually. Place BesTec™ KDW on filters as needed. Plant as site conditions permit using Armaflor™ Plant-Plugs or the vegetation-carrier Composit™.
Typical uses
LimitationsBesTec™ KDW require the use of heavy equipment for installation. BGS offers to review your site to advise you on the applicability of the product. Engineering firms may order technical specifications for calculations.  |
