Waterproofing and roofs

Leaks are not fixed with a patch: we find the source and repair the roof or terrace with the right system —membrane, polyurethane or asphalt sheet. We close the problem and back it with a written guarantee.

Roofs and terraces

Waterproofing of flat and pitched roofs and walkable terraces, with insulation if needed. We repair or renew depending on the condition.

Tiled roofs

Rehabilitation of tiled roofs, replacement of the covering, support reinforcement and valleys and gutters. We stop leaks before they damage the structure.

Pools

Waterproofing and lining of pools, leak repair and tune-up of the pool shell. We have experience in pool work from start to finish.

How we find the leak

Before touching anything we inspect the roof or terrace to understand where and when the water gets in: often the damp patch appears far from the real leak point. We check joints, drains, junctions and downpipes, and only then decide whether a localised repair is enough or it is worth renewing the whole membrane. That way we avoid patches that fail again soon.

Guarantee and maintenance

We deliver waterproofing work with a written guarantee and tell you the basic maintenance —cleaning drains and checking joints— so the roof lasts. In communities and premises we can carry out periodic checks to get ahead of problems.

Finding the leak before repairing

Before touching anything we inspect the roof or terrace to understand where and when the water gets in: often the stain appears far from the real leak point. We check joints, drains, junctions and downpipes and only then decide whether a localised repair is enough or it is worth renewing the whole membrane. That way we avoid patches that fail again at the first heavy rain.

Waterproofing systems

We choose the right system for each case: asphalt membranes, EPDM rubber membranes, liquid polyurethane or mortars, with or without added thermal insulation. There is no single solution for everything; the decision depends on the state of the substrate, the use of the roof (walkable or not) and the slope. We apply each system with the substrate preparation and overlaps that guarantee it lasts.

Flat roofs and walkable terraces

We waterproof flat roofs and walkable terraces, with their paving, their falls towards the drains and the insulation that improves building efficiency. We resolve the junctions with parapets, walls and machinery, which is where most leaks occur. A well-waterproofed terrace is enjoyable and protects the home below for many years.

Tiled and pitched roofs

We rehabilitate tiled roofs: replacing the covering, reinforcing the support, valleys, gutters and downpipes. We stop leaks before they damage the timber structure or the slab, and improve insulation while we are at it. A well-rehabilitated roof avoids the chain damage water causes when it gets in unseen until the problem is already big.

Pools and tanks

We waterproof and line pools, repair leaks and tune up the shell, and resolve tanks and buried elements. We have experience in pool work from start to finish, so we understand where they fail and how to leave them watertight and well finished. A leaking pool loses water, damages the surroundings and drives up costs; sealing it well is an investment that pays off quickly.

Guarantee and maintenance

We deliver waterproofing work with a written guarantee and tell you the basic maintenance —cleaning drains and checking joints— so the roof lasts. In communities and premises we can carry out periodic checks to get ahead of problems, because in waterproofing it is always cheaper to prevent than to repair the damage once the water has got in.

Insulation alongside waterproofing

We use the waterproofing to improve the thermal insulation of the roof, one of the areas where most energy is lost. An inverted roof or insulation under the membrane improves the comfort of the top floor and reduces climate spending. Doing both at once is far more cost-effective than tackling them separately later.

Communities, premises and individuals

We waterproof for residents associations, premises, units and private homes. In communities we prepare clear quotes for the meeting and work with the manager; in premises and units we resolve large-area roofs without stopping the activity. Each case has its system and logistics, which we adapt to the type of roof and the use of the building.

Fixed quote and guarantee

We give a fixed written quote and a guarantee on the waterproofing work. In this trade the result shows over time and with the rain, so we stand behind what we build and remain reachable. We prefer to do the job right once —finding the source and renewing what is needed— than returning each season to cover the same leak with a patch.

Prevention is cheaper than repair

Water that gets in unseen damages slabs, installations and finishes until the problem is big and expensive. That is why we recommend checking roofs and terraces before stains appear, especially in older buildings. A check and good maintenance of drains and joints greatly extend the life of the waterproofing and avoid nasty surprises in the first heavy storm.

Drainage, drains and water evacuation

Waterproofing only works if the water drains well: the membrane is not enough, you need correct falls towards the drains, properly sized and clean drains, and downpipes that discharge without blockages. Much of the leaking we see comes from poor drainage rather than the membrane itself: water pools, finds the weak point and gets in. That is why we check and resolve the whole evacuation —falls, drains, overflows and downpipes— as part of the job, not as an add-on, so the roof or terrace also withstands the torrential rains typical of the Mediterranean climate.
