  • Installation of glazing and cladding systems (waterproofing, perimeter anchorage, exterior / interior silicone sealant(s) and tile-down).
  • Quality control fields water and air infiltrations testing of glazing systems per AAMA and ASTM test standards.

Installation of Roofing and Waterproofing System:

Having worked as forensic consultant on numerous high rises and construction managers in renovation projects of condos and homes has allowed us to identify  what works properly for moisture protection design for pool decks, planters, wall openings, parking garages, expansion joints, interstitial spaces, roofs and terraces. Early detection of potential problems and incorporation of solutions into the design documents results in savings of money, time and the invaluable reputation of our clients.

After the installation of the waterproofing and roofing materials, CONSTRUCTORA GROUP incorporate ASTM and AAMA standardized test methods to assure proper performance and warranty.

Installation of Exterior walls system:

From Portland cement stucco and paint, to stone, wood and other architectural veneers, our involvement in projects has provided the know-how and consideration towards the installation of water infiltration resistance materials and components of walls maintaining the aesthetic appeal desired by architect, and the structural integrity required by Codes.

Our primary concern during installation is the interaction between exterior vertical systems, the adjacent glazing systems and horizontal surfaces. Proper selection of transition details and materials is vital as the majority of leaks in existing buildings are these areas.

Retro-fitting and hardening of older buildings

Extensive hurricane damage to high-rise and mid-rise buildings has created major challenges for owners and developers of office buildings and multi-family condominium and apartment complexes in Florida. This has included major code changes to create building exteriors that are more weatherproof and more impact resistant.

Insurance companies, saddled with extensive damage claims costs, are increasing premiums or cancelling policies altogether, particularly on older buildings that do not meet current code requirements.

CONSTRUCTORA GROUP can provide consulting services on how to retrofit and harden older buildings in a cost effective manner so that they comply with the new codes. Building hardening will provide greater protection for the building and its residents, and add the benefit of qualifying the building for insurance premium discounts. In many cases, the insurance discount alone will pay the cost of the retrofit.
