505			_aABSTRACT: The existing land subsidence in Tonsuya, Malabon has been affecting the load bearing capacity of soils found in its area, making its characterization unsuited for building heavy structural foundations. Resolving this was identified through soil stabilization, particularly the introduction of lahar to replace a portion of the naturally occurring soil and evaluate improvements in its geotechnical properties. Various tests were performed on four (4) soil-lahar mixtures – all conforming to ASTM standards – to determine their strength capacities, shear, settlements, expansion and shrinkage potentials, and degrees of compaction. Results showed that the strength capacity of the mixture decreased as the percentage of lahar replacement increased (qu = 519.7 kPa to 405.9 kPa). The maximum dry unit weights (Ydmax = 13.07 kN/m3 to 14.229 kN/m3) and optimum moisture contents (OMC = 33.11% to 22.21) of the samples were linear, whereas lahar is increased, Ydmax also increased while OMC decreased. All samples were determined to be non-to low expensive soils with very low expansion potentials (EI = 1.496 to 0.945). Their shear strengths escalated as more lahar is appended (c = 51 kPa to 3.5 kPa; 0 = 26o to 34o). The mixtures were classified under very slightly compressible soils, indicating that settlement is reduced as lahar is decreased (Cc = 0.0070 to 0.0100). Results confirmed that lahar is an effective soil stabilizer in terms of improving Atterberg limits, Ydmax and OMC values, and compressibility of soils. Findings ultimately identified 85% Malabon soil + 15% lahar proportion display the highest degree of improvement among all samples. Although identified as such, it was declared that lahar from Mt. Pinatubo did not provide an overall improvement in the geotechnical properties of Malabon soil applicable for soil stabilization.
