3D Automatic Crack Inducer Calculator
To make our customer's life easier, we made a 3D Automatic Crack Inducer Calculator solution, which calculates the quantity of all WPM® construction joint profiles. Just add height, length, and width. The calculator is interactive and can be viewed 360 degrees from any angle.
In addition, we are working on a next-generation calculator so we can add the whole concrete structure plan with the pipe and cable penetrations.

MORE ABOUT THE MATERIALS
used in the "white tank" waterproofing system
WPM® Crack Inducing Waterstop
In 2008, we started to use crystalline admixture in hopes of solving our problems with shrinkage cracks due to the fact that it can grow together to 0.4mm cracks. When engineers calculated 0.2 to 0.3mm cracks to 1m of the reinforced concrete structure in the construction design, it seemed like a perfect fit at the time.
When we understood that some cracks open more than 0.4 mm and that crystalline admixture could not grow them together, we designed a solution for controlling the shrinkage of reinforced concrete structures so that the cracks produced by the shrinkage are immediately watertight at the desired location. We added a keyway shape to the profile to make the joint connection stronger so that it can be used in load-bearing structures.
In addition, as the crystalline admixture can not grow together dynamic cracks that open and close, the WPM® CRACK INDUCING waterstop allows that movement to happen, making dynamic cracks watertight.
WPM® Metal Sheet Waterstop
WPM® METAL SHEET WATERSTOP profiles, i.e., waterstops, are designed to waterproof construction joints. Compared to alternative solutions, the metal sheet is more reliable and long-lasting. We have added polymer coating to make concrete and metal sheet connections stronger and reliable.
WPM® Waterstops works with up to 2.4 bar of positive water pressure.

Crystalline waterproofing admixture
The crystalline admixture gives the concrete a “self-healing” ability. With the water entering the crack, the admixture can close the static cracks in the concrete with an opening width of less than 0.4 mm.
When the crack is under constant dynamic load, i.e., moving constantly, the admixture can not heal shrinkage cracks. In that case, we need a solution that enables the concrete block to move and waterproof the cracks that the moving has made. For that, we made WPM® Crack Inducing waterstop.
Crystalline admixture is packaged into a soluble bag, which makes the mixing process easier and with zero waste!
WATERPROOFING STEP-BY-STEP PROCESS
in the integral, i.e., "white tank" waterproofing system
WPM® Crack Inducing Waterstop
WPM® Crack Inducing waterstop profiles are added to the concrete structure to control shrinkage cracks.
Using our 3D Automatic Crack Inducer Calculator's plan, the instalment of the profile is easier than ever, because it shows exactly where to install the profile by a cm.
WPM®
Metal sheet Waterstop
Construction joint profiles are added just before the casting process to prevent water infiltration from the construction joints.
Using our 3D Automatic Crack Inducer Calculator's plan, the instalment of the profile is easier than ever.
Crystalline admixture to concrete mix
Crystalline admixture is mixed to the concrete in the concrete factory. We use crystalline admixture in soluble bags so it can be inserted to the mix conveniently and with no waste.
Concrete casting
Concrete that is mixed with crystalline admixture is being pored after all the construction joint profiles and crack inducing profiles are installed.
Concrete structure is waterproof after casting proccess!
There is no need to add an additional membrane to the outer layer of the structure - unless the underground part is used as living quarters.
If there will be any cracks crystalline admixture in the concrete will grow it together (cracks up to 0.4mm)
ADDITIONAL MATERIALS
we use to waterproof all extra necessary components
KRASO -
Pipe Penetrations
Kraso pipe penetrations and sealing elements, makes it easy to penetrate pipes and cables through concrete walls without water infiltration.
BeSealed -
Plugs and Rings
BeSealed hydrophilic plugs and rings allow us to waterproof concrete cracks around formwork spacers and formwork spacers themselves.
WFP Injection System
Using as a backup addition to construction joint waterstops, allows to inject injection resign to close all openings in construction joint to stop water infiltration if it were to happen.
When casting 10m+ walls without WPM® Crack Inducer profile then shrinkage cracks are guaranteed to occur!
With our experience from 2008, we have seen countless times the same problem!
Shrinkage cracks appear mostly after every 4-5m.
When using WPM® Crack Inducer profile with calculated distance we can solve shrinkage cracks problem!
As we saw that shrinkage cracks appear mostly after every 4-5m we decided to try different crack inducers on the market. Soon came out some of their deficits and we decided to make our own crack inducer without the flaws.
In the picture, we can see how on a 20m wall we are using three WPM® Crack Inducer profiles with a 5m distance to control and guide shrinkage cracks while waterproofing them at the same time.
Result of the WPM® Crack Inducer profile - Controlled and waterproofed shrinkage cracks.
Here is a price comparison using the classical i.e. "black tank" waterproofing method vs integral e.i. "white tank" waterproofing method on the same underground structure:
| Waterproofing with the bituminous membrane (black tank method) | Waterproofing with crystalline admixture and WPM® profiles (white tank method) |
| Foundation floor slab | 3200m2 x 35€ = 112 000€ | 1000m3 x 3kg = 3000kg x 6.90€ = 20 700€ |
| Walls | 1700m2 x 22€ = 37 400€ | 425m3 x 3kg = 1275kg x 6.90€ = 8 797.5€ |
| Intermediate ceiling (-1) | 3200m2 x 20€ = 64 000€ | 1000m3 x 3kg = 3000kg x 6.90€ = 20 700€ |
| Intermediate ceiling (0) | 3200m2 x 20€ = 64 000€ | 1000m3 x 3kg = 3000kg x 6.90€ = 20 700€ |
| WPM® CRACK INDUCER Profile | - | 660m x 51.50€ = 33 990€ |
| WPM® Waterstops | 500m x 10€ = 5000€ | 500m x 10€ = 5000€ |
| Reinforcement | 1000m x 10€ = 10 000€ | 1000m x 10€ = 10 000€ |
| SUM | 292 400€ | 119 887.5€ |
Save on metal
As steel has risen in price, we can also use WPM® CRACK INDUCER profile to use smaller diameter rebars in constructions that does not need over dimensioning to control shrinkage cracks.

What are YIT Latvia's thoughts about the "White Tank" solution in general?
"We like that materials were easy to handle and install. The best part is that there was no pasting and plastering of anything, pure and quick work! The turnover time was faster than we were used to before which was just a bonus for us! "
Does YIT Latvija plan to continue using "White Tank" waterproofing solution in cooperation with Primostar SIA?
"When we can we definitely will! The solution is quick and easy and the Crack Inducers are genial for controlling shrinkage cracks!"
