Product Description
CKS always focus on technical innovation and product diversification to meet all kinds of customer’s need. CKS has developed new drainage system combined waterproofing, drainage and protection. This product integrates the modern technologies of film-separator waterproofing and drainage, advanced technologies of synthetic materials and processing molding.
Its piano-convex structure separates the base and the surface layer and forms a integral inter space among dense pivots that eliminate the stress and water press. The inter space has the functions of drainage, insulation, soundproofing, ventilation and braiding. The HDPE sheet has high physical function of weather resistance, shock resistance and wear resistance, and has chemical stability. Its installation and application is quickly, safely and environment friendly.

QIFENG advantages
1.Excellent selection of raw materials - our HDPE (High Density Polyethylene)
(1)HDPE (High Density Polyethylene) chemical properties is extremely stable,Acid and alkali Resistance anti-plant thorn, flexibility is very good, excellent resistance to tearing ability, excellent impact resistance, impermeable, airtight, performance is not affected at low temperature (-40 ℃), the use of performance remains unchanged over a hundred years in the ground , complete with buildings life.
(2)HDPE (high density polyethylene) to compare with the other waterproof and drainage material
◣ Ps (Polystyrene): There are obvious shortcomings, poor flexibility, very brittle, easily broken, poor impact resistance.
◣ HIPS (high impact polystyrene-resistant): improved impact resistance, HIPS drainage board poor performance in terms of tear, easy to break, easy to tear, hard surface, easy to pierce the lower part of the waterproof layer.
◣ HDPE (High Density Polyethylene): extremely stable chemical properties, acid and alkali, low temperature flexibility is very good, excellent resistance to tearing ability, good impact resistance. Use the same performance over a hundred years in the ground.

2.Unique bosses parallel design, great high drainage efficiency
Unique bosses parallel distributed design greatly enhance the drainage efficiency, far better than the orthogonal projection due to lack of distribution design compressive strength design.

3.Closed-performance welding process, to ensure a good waterproof effect
Non-flat design lead lap poor sealing, causing dislocation occurs easily during the construction, which can not effectively complete drainage and protection. Lock overlap in the construction process often because grassroots irregular, causing large deformation results can not overlap. Odd sealed plate welded design waterproofing and drainage board construction factors reduce the dislocation caused by the greatest extent, to ensure excellent tightness entire anti-drainage system.

4.Big wide standardization of product design, short construction period, to ensure the construction quality and efficiency.
Up to 2.3m wide large standardized product design minimizes overlap and improve the tightness and security of the system, to ensure the construction efficiency, while reducing construction costs.
5.Boss enhance the design, compressive strength is more remarkable.

Sidewall protection waterproofing system
1.Conventional underground construction side wall waterproof layer of protective material requirements and problems
(1)"underground waterproof technical specifications" GB50108-2008 clearly defined underground construction waterproof layer must be soft sidewall protection.
(2)half-brick masonry protection cost is high, complex construction, belong to a semi-rigid waterproof protective layer, do not permanently affixed to the appropriate protection.
(3) polystyrene board (EPS), or extruded plate (XPS) protection due to the small area of a single block of material, backfill easy to drop or perforation. Easy to absorb water, buried in the soil for a long time strength decreases, it can not play a protective role.
The above two methods can not be on the side wall underground construction waterproof layer acts lasting and effective protection,In some areas underground construction sidewall insulation,even asked insulation materials should be completely isolated from water, which is a common side wall protective layer can not be done.
