Easy to stop partial leaks!

・Big construction work is required due to partial leakage.

・The cause of the leak cannot be identified.

Construction work in condominiums is too much of a burden on the tenants.

We can solve these problems!

What is M.C.M. (Miracle Cement Maker)?

M.C.M. water sealing mechanism

M.C.M. is a waterproofing waterstop material composed of potassium silicate.

It is one of the best waterproofing materials among inorganic permeable modifiers.

When the main material, potassium silicate, penetrates deeply, it reacts with the calcium hydroxide in the concrete to form a resilient calcium silicate waterproofing layer.

It creates a resilient calcium silicate waterproofing layer, which fills countless water channels and exhibits a waterproofing effect.

Because it hardens quickly, it is also a powerful tool for creating simple roads.

Here is the charm of M.C.M.

A new concept of using concrete itself as a thick waterproof layer!

Point.①

Amazing water stopping power

It reacts quickly with the material and has an immediate effect. Seepage leaks caused by minute cracks are easily stopped after spraying. In addition, even after the reaction, the material is resilient, so it is resistant to vibration and stops water for a long period of time.

Point.②

Waterproof guarantee for up to 20 years*

High performance allows for a long-term warranty. We guarantee waterproofing for both new construction and renovation.
*This is a federated guarantee by our company and the construction company.

Point.③

Easy to install

No large equipment or tools are required. The construction period is significantly shortened, making the process inexpensive.

Point.④

self watertight reaction

After drying, the residual potassium silicate reacts with rainwater to again stop water. The more it rains, the stronger the waterproofing effect becomes.
The more it rains, the stronger the waterproofing effect becomes.

Potassium Silicate" and "Sodium Silicate," which are similar but not the same

Conventionally, water glass is mainly a “sodium silicate” process.
M.C.M. mainly uses “potassium silicate. It may seem like a small difference, but the result is a big difference.

This is what makes M.C.M. different!

Construction in condominiums and other buildings is a burden on the tenants.

In the case of a condominium or other such property where there are tenants.

Corridors must be restricted during construction

Workers must repeatedly pass through tenants’ residences during construction work on balconies, etc.

The construction schedule must be coordinated with tenants and the traffic control of tenants during the construction is a heavy burden,
The burden of coordinating schedules with tenants and restricting the passage of tenants during construction can be significant.

Unable to identify the cause of the leak

Potassium silicate permeable waterproofing/waterproofing agent” reacts with rainwater when it reaches the cracks in the concrete (waterway) at the location of the leak and stops the water.

In other words, if “Potassium Silicate Waterproofing Materials” is sprayed directly above the leaking area, it is possible to reach the cracks (waterways) with rainwater and stop the water.

Short construction time for the common corridor area as well.

The water sealing and waterproofing installation can be completed in a few hours.

And once construction is complete, the road can be opened to traffic immediately.

Balcony can be shut off in a short time

Similarly, water sealing and waterproofing of balconies can be completed in a few hours.

No large tools are required, and traffic in the resident’s home is minimal.

Thus, the burden of water sealing and waterproofing is reduced!

The lumber design price is remarkably economical and requires no skilled labor or special equipment or tools.

The design price of materials and labor is as economical as 2,300 yen per square meter for 100 square meters in one construction period. Also, skilled workers, special equipment, and tools are not required.

A 10-year warranty is issued for both new construction and renovation work.

Almost no industrial waste is generated during construction.

There is no coating film, so there is nothing to remove for the next construction, and maintenance can be done easily.

No gloss or color is produced after application.

Caulking or painting can be applied to the surface after installation. Tensile test data is available.

Inhibits the formation of white flakes (efflorescence), and the inhibiting effect lasts for a long period of time.

Contains lithium nitrite, which is a rust inhibitor for steel bars, and inhibits the generation of rust juice.

Inhibits the growth of drying shrinkage cracks.

Cracks of 0.3 mm or less can be sprayed or injected at low pressure to stop leakage without any extra work.

Even if cracks become large and leak after installation, it has a self-sealing effect.

The process of self-sealing effect can be seen.

Compatible with other waterproofing materials and can be used together.

When the cause of leakage is a crack larger than 0.3 mm, it can be filled with mortar-type materials. Please contact us.

Waterproof material that can also be used as a waterproofing material.
