Slope protectors can be quickly formed into any shape suitable for the site.
TACOM is a method of forming mortar (concrete) structures of a certain thickness by injecting mortar or concrete into a lightweight, high-strength double-woven fabric (fabric formwork) made of synthetic fibers.
Taking advantage of its characteristics, it is used in a wide range of applications, such as river and dam revetment slope protection, channel lining, bridge pier rooting, slope greening, and underwater (underwater) law lining.
New Technology Information System “NETIS Registration”: Cloth Formwork Method
Registration No. KT-220091-A
*For sale only in the Japanese market
Lightweight, compact, and flexible, it requires less space than conventional construction methods such as taut blocks.
It follows the ground and can be installed in any shape.
(The maximum applicable legal slope is about 1:1.0)
Injection can be performed by simply securing the perimeter of the mat.
Injection into factory-processed mats tailored to the site enables installation over a wide area by a small number of people in a short period of time.
No large heavy equipment is required, and the work can be performed underwater (subsea).
Lay the mat on the slope. A single pipe is passed through the upper side of the slope of the mat and secured with chain blocks for support, taking into account shrinkage.
Insert the injection hose into the inlet of the mat and start from a low position. Inject the mat, taking care to keep the tip of the hose in contact with the interior mortar (concrete) at all times.
Wash spilled mortar (concrete) and dirt with water.

(1) The above formulations are standard without aggregate. Particular attention should be paid to material separation when constructing underwater.
(2) Before installation, be sure to perform test mixing.
(3) The use of admixture materials is recommended for concrete mixing.
(4) The amount of dewatering is about 15% for mortar and 7% for concrete (20 mm to 25 mm).
