SW-PU900(Crack Repair Materials) : Waterproofing basement walls from inside
Product description : Waterproofing basement walls from inside
SW-PU 900 is main element having polyol and hardening agent having MDI element, It is two liquid type hard firing urethane. It is the product forming pure high-strength urethane solid at dry process breakage part and forming partial firing solid at wet process breakage part. Owing to having superior technological feature to concrete, it is the product having excellent repair and reinforcement and being able to reinforce and index at the same time.

1. Where to use
It can be used for repairing works of cracks of subway, tunnels, dams, bridges, harbors, sewage
terminal treatments, electric power facilities, street improvement, giant concrete facilities, and
stopping all kinds of water leakage. And it also can be used for stopping water leakage and repairing
works of cracks, mixed with wet and dried surface part of the cracked leakage constructions, all
concrete constructions and buildings.
2. Specific character
This is a 2 liquid type intensified Urethane product consisted of Polyol type agent(A liquid), and
Isocyanate (liquid rubber) type hardening agent(B liquid). High intensity and high intensified foam
crystalloid is made on the dried site, and partially low foam crystalloid is made on the wet site.
As Mechanical intensity and durability is so superior, it can be used on dried and wet site all together
in all weather, and it is also a tactic product of this company.

|SEAL LEAFLET ADHESION STRENGTH||15||kg/㎠|
(Above result can be changed partially by changing the raw material of the product and improvement)
*When we carry out the dried crack site construction ,it forms the non-foaming high intensity Urethane foam.
When we carry out the work on the wet, moisturized site, partially foaming and forms the foaming
crystalloid mixed with Urethane and Urea (Carbamide). It is possible for you to order custom-made
product and according to the general conditions of the site like temperature, moisture, and the
quantity of inflowing water, the reaction time can be decided. Generally, when you are using this
company’s high intensity Urethane injection(hardening time 1-2 min) on the site where you are doing
the leakage construction with the first step foaming agent(liquid), it will be able to expect simple
construction work and shortening the working period simultaneously.
A liquid 19kg/iron can container + B liquid 21kg/iron can container is packed by 40kg/set.
5. how to use
Drilling some regular-spaced holes on the cracked part, insert packer and fix it.
Using the grouting injection pump(SWDM-2000) made by this company, put appropriate A and B
liquid into A and B injection container and do the injection work.
Use the liquid inside the container quickly, if possible. When we use it in the winter season,
the viscosity of the medical liquid can rise. In this case, heat the iron can with the hot wind or any
other heating gear and descend the viscosity of the medical liquid. Then we can inject easily.
6. How to handle and caution
Taking out the medical liquid from the container, seal up the stopper of the medical liquid container
quickly. After using the tools and the hoses, take out the liquid left inside and wash inside of A hose
and B hose with oil.
When you handle the medical liquid, be sure to wear helmet, protective goggles, and gloves. If the
face or hands are stained with the medical liquid, wash out with the soap water instantly.
