Waterproofing Solutions

Waterproofing means protecting the elements of a building against unwanted passage of liquids and / or vapours, extending its serviceable life.

Regardless of the chosen solution, a waterproofing coating should retain its characteristics when subject to mechanical actions and / or of atmospheric agents. Failure to observe this requirement may lead to high repair costs, caused by the renewal of waterproofing coating and the repair of affected areas.

Aware of the existence of numerous cases of pathologies that require later corrective interventions, RenoBuild pays special attention to detail and implementation of appropriate solutions, according to the characteristics and needs of each case. We provide the following Waterproofing services:

  • Balconies and Terraces;
  • Re-waterproofing without removing the existing coating;
  • Roofs;
  • Swimming-pools, water Tanks and Reservoirs;
  • Waterproofing of specific zones (windows areas, connecting draining tubes, etc.)
  • Facades;
  • Repairing infiltrations.



Roofs are crucial to protect a building, thus it is essential to ensure their waterproofing. Problems existing in these zones lead to the appearance of serious problems in the constituent elements of your home.

The sub-horizontal disposition of layers that form a terrace / balcony coverage makes the contact of rain more prolonged than in a roof, favouring infiltration in the support, typically in concrete. Consequently, besides the need to create the conditions needed to drain water (through a shaped layer with a minimum drop) and guaranteeing a sufficient number of downspouts, it is necessary to apply waterproofing coating with adequate characteristics for the future use of the space.



The facade of a house generally has a wide range of different elements and materials: doors, windows, joints, several coatings, etc. Each of these materials has a different performance in the presence of water: some are permeable, others are totally impermeable and others still are permeable only to vapour, but not to water. It is necessary to understand the function of each constituent element of a facade to be able to act correctly to correct or prevent the occurrence of a given pathology.



A swimming-pool is an impermeable tank with the aim of containing water, and must meet the following requirements: be watertight; bear the actions they are subject to; keep the good quality of water and meet the aesthetical standards of its users. They are generally located in the outside, thus the waterproofing systems must be resistant to atmospheric agents and agents used to treat water. In the special case of drinkable water reservoirs it is crucial to use waterproofing products does not alter water potability.

Renobuild – Facade Renovation, Monchique

Cleaning, Renovation and Waterproofing of Facades

Our Renobuild customer’s project in Monchique focused on facade renovation wherefore the first step was cleaning those same facades. For the façade restoration, we made a barrier reinforced with cement-free reinforcing and levelling material “Sto RFP” and glass fibre mesh. This mortar has a high mechanic resistance and flexibility and its application gives the facade high resistance to cracking. “Stolit K” was used as finish, waterproofing that area and keeping its high breathability index.”


“Protection against water’s destructive forces is vital during the design and construction stage of your building. Sto has a wide range of waterproofing products and solutions which covers various application areas. Buildings are exposed to weathering, aggressive harmful substances that act on the surfaces. High-performance protection systems are needed to counter these weathering effects in the long term. Durability and maintaining the value are concerns in all protection and renovation projects.”


ETICS systems (External Thermal Insulation Composite System

Project “Alma Verde” is located in Western Algarve, in the municipality of Vila do Bispo. It is formed by several ecological dwellings and has already won 23 awards for energetic efficiency, sustainability, architecture and innovation. In Project Alma Verde, Renobuild applied the ETICS systems (External Thermal Insulation Composite System) – StoThermClassic –of several buildings.

“STO was the first building products manufacturer to design and produce external wall insulation systems. Still regarded as the industry benchmark over 50 years later, StoTherm Classic has undergone five decades of development and refinement to meet the demands of modern construction and the need to reduce energy consumption around the globe.”
