Basement Waterproofing in Makati and BGC Taguig: Expert Solutions by Mackintosh Corporation
Basement water intrusion is one of the most damaging and costly problems a building owner can face. Whether you own a commercial tower, a residential condominium, or a mixed-use development in Makati or BGC Taguig, a wet or flooded basement can compromise your entire structure. Mackintosh Corporation is a licensed waterproofing specialty contractor providing expert basement waterproofing services in Makati, BGC Taguig, and throughout Metro Manila.
With deep expertise in below-grade waterproofing systems, world-class materials, and a team of highly trained waterproofing professionals, Mackintosh Corporation is trusted by property developers, building owners, and general contractors across the Makati CBD and Bonifacio Global City.
Why Basement Waterproofing Is Critical in Makati and BGC Taguig
The high-density urban environment of Makati and BGC presents unique waterproofing challenges. Many buildings in these areas have multiple basement levels used for parking, mechanical equipment rooms, storage, and retail spaces. The water table in Metro Manila is relatively high, and groundwater pressure — combined with heavy rainfall — puts basement structures under constant hydrostatic stress.
Without proper below-grade waterproofing, you risk:
- Water seepage through basement walls and floor slabs
- Hydrostatic pressure causing cracks in concrete foundations
- Corrosion of steel reinforcements leading to structural weakening
- Flooding of parking levels, elevator pits, and utility rooms
- Damage to mechanical and electrical equipment
- Mold growth and poor air quality affecting building occupants
- Expensive emergency repairs and business disruption
Investing in professional basement waterproofing from the start — or addressing existing leaks promptly — protects the structural integrity and long-term value of your Makati or BGC property.
Mackintosh Corporation: Basement Waterproofing Specialist in Makati and Taguig
Mackintosh Corporation is a PCAB-licensed Waterproofing Specialty Contractor (License No. 34979) with extensive experience in below-grade waterproofing for high-rise and mid-rise developments in Makati and BGC Taguig. The company was founded by members of the Philippine Constructors Association (PCA) Metropolitan Chapter and adheres to the highest standards of professionalism, workmanship, and material quality.
Mackintosh handles both new construction waterproofing — applied during the building phase — and remedial waterproofing for existing structures experiencing water intrusion problems.
Below-Grade Waterproofing Systems We Apply
Mackintosh Corporation selects the most appropriate waterproofing system for each project based on site conditions, structural design, water table levels, and budget. Our below-grade waterproofing solutions include:
Preprufe Self-Bonding HDPE Membrane (Positive Side)
For new construction projects in Makati and BGC, Mackintosh applies the Preprufe self-bonding HDPE membrane from GCP Applied Technologies (Grace Construction Products). This is a pre-applied positive-side waterproofing membrane that bonds directly to the concrete as it is poured, forming a permanent, self-healing barrier against groundwater and hydrostatic pressure. It is the preferred system for basement slabs and walls in new high-rise developments.
Crystalline Waterproofing (Negative Side)
For existing basements experiencing active water ingress, Mackintosh applies negative-side crystalline waterproofing systems from the Sika and Davco product lines. These systems work from inside the basement, penetrating the concrete matrix and forming insoluble crystals that permanently seal cracks, pores, and capillaries against water infiltration.
Epoxy and Polyurethane Injection
For active leaks, cracks, and joints in basement walls and slabs, Mackintosh uses epoxy and polyurethane injection techniques. Polyurethane injection is highly effective for stopping active water flow, while epoxy injection restores structural integrity to cracked concrete members.
Cementitious and Elastomeric Waterproofing
For cistern tanks, sump pits, and retaining walls, Mackintosh applies rigid and flexible cementitious waterproofing coatings that provide durable, water-resistant surfaces compatible with concrete and masonry substrates.

Frequently Asked Questions — Basement Waterproofing in Makati and BGC
What is the difference between positive-side and negative-side waterproofing?
Positive-side waterproofing is applied on the side where water comes from (outside the basement wall or under the slab), creating a barrier before water contacts the structure. Negative-side waterproofing is applied on the interior of the basement, holding back water that has already penetrated the concrete. Mackintosh applies both systems depending on project conditions and access constraints.
Can basement leaks be fixed without excavation?
Yes. For existing basements with water intrusion, Mackintosh applies negative-side waterproofing and injection techniques from the interior — no excavation required. This is a practical and cost-effective solution for occupied buildings in Makati and BGC where exterior access is not feasible.
Does Mackintosh handle both residential and commercial basement waterproofing?
Yes. Mackintosh Corporation handles basement waterproofing for all types of structures — from single residential homes to large commercial towers, condominium developments, and industrial facilities across Makati, BGC, and Metro Manila.
