Frequently Asked Questions

Limestone bedrock means most homes use shallow spread footings (zapatas) or mat foundations (losa de cimentación). No deep piles needed. Standard depth: 60–100cm. The hard limestone is actually excellent for building — it's why the Maya pyramids still stand.

Spread footings for 150m² home: $200,000–$400,000 MXN. Mat foundation: $300,000–$500,000. Foundation is 8–12% of total build cost. Excavation in limestone requires jackhammer/breaker — adds $30,000–$80,000 vs soft soil.

Yes — essential before any construction. Mechanical soil study (estudio de mecánica de suelos): $8,000–$20,000 MXN. Tests bearing capacity, water table depth, limestone hardness. Required for construction permit. Our structural engineer uses these results to design your specific foundation.

Water table in coastal areas can be 1–3m below surface. In some areas of Tulum: 0.5–1.5m. This affects foundation depth, basement feasibility (usually not recommended), and waterproofing requirements. Soil study reveals exact depth for your lot.

Limestone is porous — water rises by capillary action. We apply: 1) Waterproof membrane on all below-grade concrete. 2) Capillary break layer (gravel + vapor barrier). 3) Waterproofing admixture in foundation concrete. 4) French drains around perimeter. This prevents moisture migration into walls and floors.

Our 6-Step Process

01
Soil Study

Mechanical soil study determines bearing capacity, water table, rock hardness. Essential for structural design.

02
Foundation Engineering

Structural engineer designs foundation based on soil study, building loads, and seismic/wind requirements.

03
Excavation

Jackhammer and excavator work through limestone. Level to grade. 3–7 days depending on lot size.

04
Rebar & Formwork

Steel reinforcement cage tied per structural plans. Forms set for concrete pour. Independent inspection.

05
Concrete Pour

Foundation concrete poured in single continuous pour. Vibrated to eliminate voids. Minimum f'c 250.

06
Curing & Waterproofing

7-day wet curing. Then waterproof membrane application. French drain installation. Ready for structure.

Materials Guide for Tropical Construction

Tropical-Approved
  • Structure: Reinforced concrete 4,000+ PSI, epoxy-coated rebar
  • Windows: Hurricane-rated aluminum with impact glass
  • Flooring: Porcelain tile, polished concrete, tropical hardwood
  • Exterior: Chukum plaster, natural stone, marine-grade coatings
  • Carpentry: Tzalam, chechen, parota (natural termite resistance)
Materials That Fail
  • Drywall: Mold within months in 80% humidity
  • Untreated wood: Termites destroy in 2–3 years
  • Standard steel: Salt corrodes in 3–5 years
  • Carpet: Permanent mold in tropical climate
  • Asphalt shingles: Can't withstand Category 5 hurricanes

5 Costly Mistakes to Avoid

  1. No fixed-price contract — Verbal agreements = 25–40% cost overruns. Demand itemized contracts.
  2. Ignoring hurricane codes — Retrofitting costs 3× more than building right. NOM-031 compliance is mandatory.
  3. Skipping environmental permits — SEMA clausura = forced demolition. We have 100% approval rate.
  4. Hiring 5 separate contractors — Coordination failures + blame game. Our in-house team covers everything.
  5. No waterproofing plan — 1,200+ mm rain/year + high water table = guaranteed leaks without proper membranes.
