Rapid Setting Water Plug Mortar
A rapid setting water plug mortar composed of special blend of hydraulic cements, fillers, graded fillers and chemical additives. MUREX is a dry powder that when mixed with water, quickly sets and expands as it cures to provide a permanent watertight seal thereby stops rapidly active water leaks and seepage holes and cracks in concrete and masonry.
It does not promote corrosion on the reinforcements since the material contains non-metallic aggregates and non-corrosive agents.
Packaging:
MUREX is supplied in 5 kg bags.
Consumption:
1.9 kg to fill volume of one liter.
Storage:
Protect the material from all sources of moisture and frost.
Shelf life:
6 months from the date of production if stored properly.

Surface Preparation
Clean carefully the surface to be treated. Holes, cracks and fissures must be widened to assure a better anchorage of the product. Chisel out the leaking area to a minimum width and depth of 20 mm. It is recommended to cut the sides in a square-shaped manner, avoiding cutting it into a vsection. Make sure that all loose materials are removed.
The surfaces to be coated must be clean and free from dust, oils, grease, laitance, curing compound. When necessary, sand or shot blast, wet blast or high pressure water wash the area to be treated in order to ensure that all foreign matters and other surface contaminants are completely removed.
Mixing
Add MUREX to 24% of clean water and mix the product in a suitable mixing drum by hand or with a clean rod till a homogeneous malleable mixture is obtained.
Due to the rapid set characteristics of the product, prepare only a quantity of mortar which can be placed within the prescribed set time.
Application
After mixing, wait for about 10 to 15 seconds until slight warmth is felt. Press the product with strength into the crack, maintaining the pressure till the initial set is reached (about 45 seconds).
Smooth the plugging, and remove the excess product.
Always start to treat the leaking surface from higher point down towards the lower part till the leakage is totally stopped. Waterproofing products, if required, can be applied afterwards.
In case of general seeping from all over the surface, apply MUREX as a powder and spread it on the surface in a way to guarantee the blending between the powder and the seeping water.
To treat a leakage under high pressure, insert a plastic tube into the deepest possible point inside the crack to act as a drainage tube. Apply MUREX around the tube to eliminate the leakage area. Remove the drainage tube and proceed with the final blocking of the leakage.
To block the widespread pressure leakage, insert a plastic tube into the point of maximum leak and then apply MUREX.
Cleaning
Clean the tools immediately after use with clean water. During work, it is recommended to place the tools in water while not in use.
Recommendations
MUREX is a cement-based product.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately.
Do not induce vomiting.
