EXISTING CONSTRUCTION WATERPROOFING Technical proposition of permanent waterproofing of existing underground reinforced concrete walls with PENETRON® system – Active crystal formation with penetrating action above one meter in depth EXISTING CONSTRUCTION WATERPROOFING Surface preparation, repair and waterproofing existing surface of reinforced with the PENETRON® system. Application on the internal side (negative) 1. System application on the walls Depending on the working procedures, concrete surface can be treated and cleaned by a high pressure jet waterblasting (300-500 bar), for better visual contact with faulty areas. Then, the water leaking cracks can be sealed with the rapid-setting crystalline waterproofing plug PENEPLUG® (mix with minimum water until the texture is as dry-earth). For a better application of PENEPLUG®, cracks should be routed out with mechanical means, up to 2 – 3 cm in width, in a conical shape, for better anchoring of the rapidsetting plug, during

the application. Cold joints can be treated in a similar way, by cutting on both sides of the joint with mechanical means and creating a wedge, 3 cm in width. Next, rapid-setting plug PENEPLUG® is applied. In some cases, depending on the work schedule, PENEPLUG® can be used as a waterplug, prior to waterblasting, but only after PENEPLUG® has reached its mechanical strength. It must be pointed out, that 1 – 2 layers of the integral crystalline waterproofing coating PENETRON®, at a mixing ratio of 5 parts PENETRON® powder to 3-3.5 parts water (by volume), must be applied on PENEPLUG®, by brush, while the latter is still “tacky” and the total consumption of PENETRON® mixture is 1.5 kg/m 2 in total for 2 layers. 2 EXISTING CONSTRUCTION WATERPROOFING 2. Repairing and waterproofing of honeycombed and spalled areas, according to the following procedures Cracks, honeycombed and spalled areas, of new or existing concreting, should be routed out with mechanical means, to remove

dirt, loose materials and aggregates. Clean honeycombed areas with excess water, to remove loose materials and moisten the surface to a dull dampness, which is prerequisite for the application of PENETRON® integral crystalline waterproofing system. When the concrete is damp, with no wet sheen on the surface, apply a slurry coat of PENETRON®, at a mixing ratio of 5 part PENETRON® powder to 3-3.5 parts of water (by volume), on the areas to be patched or repaired and 2/5” (10 mm) around them. While PENETRON® coating is still “green” (tacky), mix PENECRETE MORTAR™ with adequate amount of water, until the desired consistency is achieved [usual mixing ratio is 4.5 parts of PENECRETE MORTARTM to 1 part of water (by volume)] and filling the cracks and spalled areas. When PENECRETE MORTARTM has set, but is still moistened, apply a second layer of PENETRON® slurry coat, at a mixing ratio of 5 part PENETRON® powder to 3-3.5 parts of water (by volume), on the repaired areas. At this

stage, if waterproofing of the total construction is required, apply a slurry coat of PENETRON® on the whole surface, in two layers, while the first layer is still “green” (approx. half to one hour later). In lots of applications, to save time, the first layer of PENETRON® is applied post to surface preparation and dampening and approx. half an hour later, while the product is still “green”, the repairing mortar PΕΝΕCRETE MORTARTM is applied. Approx. half to one hour later, and while PΕΝΕCRETE MORTARTM is still “green”, the second layer of PENETRON® slurry coat is applied. The total consumption of the two layers of PENETRON® is 1.5 kg/m2. 3 EXISTING CONSTRUCTION WATERPROOFING 3. Repairing and waterproofing of tie holes and pointing applications, according to the following procedures Tie holes must be repaired, as mentioned below. Areas should be chiseled back to sound concrete, by mechanical means and the area of 1.4’’ (35 mm) around them and metal formwo

rks must be removed or, at least, sawcut and routed out at a reverse wedge of 1.2’’x1.2’’x1.6’’ (30 x 30 x 40 mm). Clean areas with excess water, to remove loose materials and moisten the surface to a dull dampness, as mentioned above. When the concrete is damp, with no wet sheen on the surface, apply a slurry coat of the integral crystalline waterproofing coating PENETRON®, on the areas to be patched or repaired and 2/5” (10 mm) around them, at a mixing ratio of 5 part PENETRON® powder to 3-3.5 parts of water (by volume). While PENETRON® coating is still “green” (tacky), mix the integral crystalline repairing mortar PENECRETE MORTAR™ with adequate amount of water, until the desired consistency is achieved [usual mixing ratio is 4.5 parts of PENECRETE MORTARTM to 1 part of water (by volume)] and filling the cracks and spalled areas. As mentioned above, when PENECRETE MORTARTM has set, but is still moistened, apply a second layer of PENETRON ® slurry coat, at a m
