Framework

Classic fascine mattresses are often big and enormously heavy. That is why they are made on pipes, which enables them to slide smoothly and undamaged into the water. A tugboat or crane ship can move the fascine mattress to the desired location with tow lines.

First of all, a framework of faggots is constructed for the first layer, and then a second layer at right angles to the first. Each intersection is secured with lashing rope, which also forms the basis for further tying the brushwood to the fascine mattress. The lashing rope contains sisal-polypropylene which tightens when wet.

Sustainability and environmental friendliness

Next, brushwood bundles are evenly distributed between the top layer of faggots to a thickness of 10 to 15 cm. A second layer of brushwood is placed on top of these, at right angles to the first layer. The customer determines the thickness of the faggots and the layer of brushwood. The customer could be: Rijkswaterstaat (Directorate-General for Public Works and Water Management), a municipality or a contractor.
