Penetron System Instructions | How Penetron waterproofs cracks and concrete
The PENETRON system works on a basic yet most efficient principle.The waterproofing effect is provided by reaction of the various chemical components contained in the solution when combined within the matrix of the concrete.The chemicals penetrate deep into the capillary tracts of the concrete by pressure of osmosis.Varied chemicals combine to form crystals which close the capillaries and shrinkage cracks to drive out moisture.This process is performed with or against the pressure of water.In the absence of moisture PENETRON components lie dormant.Should moisture be contacted again at any time,the chemical action and sealing process repeats itself automatically and advances further in-depth into the concrete.That is to say PENETRON chemicals will continuously seal and reseal due to their chemical nature.Crystalline growth from capillary waterproofing has been measured as deep as 3 feetfrom point of application.
There are many different types of waterproofing materials in the market.Today we look at a very effective water proofing material called PENETRON.
PENETRON becomes an integral part of the concrete,forming with the concrete to become a complete body of strength and durability.PENETRON Waterproofing and Protection Systems are 100% compatible with concrete.
PENETRONE crystalline formation will not allow a water molecule to pass.However it does allow the passage of air,enabling the concrete to breath and thoroughly dry,eliminating water vapor build up.
PENETRON,in addition to being the most effective permanent waterproofing system,also provides a wide range of protection from freeze-thaw cycles,corrosion of reinforcement,aggressive sub-soil waters,sea water,carbonates,chlorides,sulphates and nitrates,(PH 3-11 constant contact,PH 2-12 periodic contact)
WHERE PENETRON SHOULD BE USED
PENETRON is recommended for use in any concrete or block structure where it is required to keep water in or out.PENETRON should be applied to concrete or block structures where potential risk of water or chemical attack is possible.
PENETRON becomes an integral part of the concrete and thus ensures permanent waterproofing amd protection.Its capability of being applied from either the positive (side exposed to water) or the negative (side opposite the water) allows for virtually any and all waterproofing requirements.

Wood parquet floor, is a floor made of short strips of wood,the strips gives a beautifully pattern on the floor.The best strips of wood strips are one made of hardwood, common are mahogany wood parquet.
What can a cause wood parquet to come off?
Wood parquet worst enemy is water or moisture. If water or liquid spills on parquet and left on the surface and manages penetrate beneath the parquet, the wood may absorb water and warp, this will weaken the adhesive bond between the parquet and floor screed hence the strips may start to come off. In case the moisture was caused by a leaking plumbing or drainage pipe, and then the pipe has to be fixed first, before repairing the wood floor.
The adhesive is spread on floor screed and parquet strips lay on the adhesive. If the cement screed was not done well, the parquet won’t last long, it will come off. Some of floor screed defects are.
Poor cement sand ratio. When ratio is week, parquet strips won’t stick on floor screed, actually the floor screed will come off with parquet stuck to it.
Un even floor screed will show on the laid parquet, lifespan of the parquet on uneven floor is very short.
Planning for the wood parquet repair.
- If you are buying new parquet, then the parquet to be replaced should be of the same design and type as the old type. In the market the most common types are the three finger and five-finger wood parquet.
- Buy the right adhesive, specifically manufactured for wood floor.
- Get the right carpenter for the job.Qualified and experienced.
Steps to repairing wood parquet
Step 1.Removing the damaged parquet.
Check out the floor for any movement or uneven surface. Carefully remove the damage parquet; if it’s a small area then care should be taken, while removing the parquet, because the same will be put back on the floor, if its big area then new one maybe bought.
Step 2.Leveling the screed.
Make sure the ground receiving the parquet if evenly leveled. If the cement screed has come off then it should be repaired with the right ratio of cement sand screed and left to dry before applying the adhesive.
Step 3.Clean the floor screed.
When the floor screed is completely dry, remove all dust or dirt on it, so that the glue can bond well with the cement screed.
Step 4.Re-installing the wood parquet.
After checking the existing pattern, spread the right amount of adhesive glue evenly on the floor. Lay the parquet, following the pattern. Try to reduce the gaps between strips as much as possible.
Step 5.Sanding and Sealing the wood floor.
Sanding is done 24hours after re-installing the wood parquet on floor. The first sanding, use the rough sand paper. Mix the wood waste from sanding with the parquet adhesive and fill the gaps between the strips, wait for around 30 minutes and sand it down. Use the smooth sand paper for the last sanding.
NB.It’s always advisable to sand the entire area; the new and old parquet should be sanded, for a uniform finish.
Step 6.Polishing the wood floor.
When the floor is dust free, apply first coat of the right vanish made for wood floor. Let it dry and apply another coat to give it the gloss required.
