The excellent properties of Insuwrap waterproofing membranes are particularly welcome in areas where there is a risk of subsidence or where the soil is very light and permeable to water.

The membrane has a high elongation at breaking point, high tensile strength and great resistance to surface pressure. Another important advantage, is quick and simple installation. The pond can be filled with water immediately.

2. Site Preparation
After the basin is excavated, the surface of the excavated area should be free from sharp objects. If the surface consists of coarse particles, a layer of fine sand should be spread on top. Water inlet and outlet pipes will be provided. The membrane is joined to inlet and outlet pipes by means of flanges to ensure a tight seal.

3. Application on Basin's end
For the upper fastening of the membrane, a circular trench should be excavated around the basin ( about 40 cm width and 30cm depth) INSUWRAP membranes are installed covering the bottom of the trench and applied towards the basin.
After the membrane is placed in position inside the circular trench the trench is filled with the excavated soil or concrete.

4. Waterproofing membranes (type L / LR-UV)
The membrane could be rolled out on the prepared surface, aligned and cut to the required length. The surface must be smooth, otherwise; a protection layer is required. The protection layer can be fine sand or non woven polyester (140 gm/m2). If the required liner is ultra violet resistant and reinforced (LR-UV) there is no need to cover it, otherwise; it should be covered by soft sand for horizontal surface and sand and gravel for sloped one (Type L) It is also possible to prefabricate waterproofing liners from INSUWRAP membranes if the shape of the surface of the basin is certain and known.

5. Dressing to pipes and drains
Apply Insurbond-106 contact adhesive to pipes outlets and around the drains and to the Insuwrap PVC waterproofing liner and then contact liner to the pipe and drain. Clamping rings shall be placed at the top end of the liner, sealant is then applied all around the pipe where the PVC ends.

6.  Flood Test
Flood test consists of maintaining water over the entire surface, for a period of 24 hours. In case of any leakage the source of leakage will be determined. Water will be drained and repair works will be carried out in the affected area. As per requirements, water test will be repeated.     

Agricultural Purposes
Proposed scope of work for
INSUWRAP PVC Lining System for
Playing Fields of Stadiums

General  :
Insuwrap offers waterproofing membranes for lining of playing fields in stadiums & playgrounds to prevent water permeability. Installation is economical due to the minimum civil work and site preparations required to install the Liner.


Site Work :

1. The sand of the playing field area should be leveled and compacted.
    

2. Insuwrap PVC " L" lining membrane will be installed all over the playing field as well as the sides & bottoms of the trenches. PVC membrane will be 50 mm hot air welded at overlaps to provide a continuous sealed PVC system.
    

3. Polyethylene protection layer, 500 micron, to be installed above all PVC liner.
   

4. Gravel (4 - 5 cm) thick to be spread in the trenches to receive drainage piping & sprinkling systems (specified by manufacturer).
    

5. 200 mm thick agricultural soil mix to be spread all over the field. Field is ready to receive natural grass layer.
