75mm to No.10 sieve

GRAVEL

No.10 to No.40 sieve

COURSE SAND

No.40 to No.200 sieve

FINE SAND

passing No.200 sieve

SILT CLAY PARTICLE

soil, crushed stone, and sand used to raise an existing grade, or as a man-made-deposit; generally used under footings, pavers, or concrete slabs on grade; classified under the Unified Soil Classification System (USCS) as:

FILL MATERIALS

soil materials with sand equivalent of not less than 50%; used to prevent the movement of fine particles out of soils and other natural materials through which seepage occurs; conforming to ASTM C 33, size 67.

FILTERS

selected laboratory-approved pit-run gravel, disintegrated granite, sand, shale, cinders or other similar materials with not more than 35% fraction passing the No. 200 sieve.

BORROW FILL

hard durable fragments of stone and a filler of sand or other finely divided mineral matter, free from vegetable matter and lumps of clay, complying with the following AASHTO METHODS T-11 and T-26 Grading

BASE COURSE MATERIALS

P5,000 per 15 16 cum – BULIK (for Riprap)

ESCOMBRO

a constructed layer or facing of stone, placed to prevent erosion, scour or sloughing of a structure or embankment.

RIPRAP

consists of mats or baskets fabricated from wire mesh, filled with small riprap, and anchored to a slope.

GABION SYSTEM

GEOSYNTHETICS Construction materials consisting of synthetic components made for use with or within earth materials generally are referred to as geosynthetics. Geosynthetics can be further categorized into the following compo

Geotextiles Geomembranes Geocomposites Geonets Geocells

are the most common geosynthetics, and consist of woven or nonwoven fabric made from polymeric materials such as polyester or polypropylene generally used for reinforcement, separation, filtration, and in-plane drainage.

GEOTEXTILE

when the geotextile fabric lends its strength to low load- bearing soil to increase the overall design strength and decrease the amount of sub-base and base course material.

REINFORCEMENT

when the geotextile is placed between dissimilar materials to prevent migration of one of the materials into the other.

SEPARATION

when the geotextile is used to prevent the movement of fine particles from soil through which seepage occurs

FILTRATION

those employed to protect cut slopes or drainage features. When used in conjunction with a stone lining or riprap, they would serve a secondary function of separation.

FROSION CONTROL

are exclusively those used for silt fence applications. While they serve the purpose of "filtering" runoff, the mechanism by which they function is different than subsurface drainage or erosion control applications.

SEDIMENT CONTROL

Different types of geomembranes have significantly different properties including :

Strength Longevity resistance to ultraviolet light thermal expansion chemical resistance, ease of installation

consist of a combination of geosynthetic components; are usually sheet or edge drains consisting of a prefabricated core to which a geotextile filter is bonded

GEOCOMPOSITES

is a type of geosynthetic that consists of a continuous extrusion of polymeric ribs that form void space through which provide in-plane flow capacity. Geonets are available with or without bonded geotextile filters. Geonets with bonded geotextile filters are sometimes referred to as composite drainage nets

GEONETS

are three-dimensional prefabricated polymeric systems ranging from 100 to 200 mm (4 to 8 inches) high. The geocell systems are collapsed for delivery to the site. Upon arrival at a site, they are spread open and filled to form a three-dimensional reinforced mattress.

GEOCELLS

prevent termites from accessing the wood in a home. There are a variety of methods:

PHYSICAL BARRIER

- a layer of sand with uniform size particles. The sand must be large enough to prevent the termite from moving through it effectively and of a consistency that prevents its use in "tunnel"

TERMITE RESIST SAND

steel mesh product that is fine enough to keep even tiny termites from passing through it. Termite Mesh is used in slab construction (concrete slabs are poured over or with the mesh). It is also used to wrap pipes and other access areas.

TERMITE MESH

in particularly high-risk termite environments, homes are sometimes designed on high concrete pillars to physically separate the home from the distance termites can travel from their colony.

HOME CONSTRUCTION

The objective of this method is to establish a continuous termiticide barrier or treated area between potential soil access routes and the structure to either kill or repel subterranean termites that attempt to reach the structure. A termiticide is a type of chemical used to control termites.

CHEMICAL BARRIER

involves drilling through the slab floor and injecting termiticides into the soil at regular intervals.

SLAB TREATMENT

trenches are dug around the foundation, termiticide applied and the trench filled back in. Chemicals may also be injected into the soil in the crawl space/basement and around the foundation. The walls and foundation of the home are also treated, as well as around piers, pipes, and other access point.

BASEMENT AND CRAWL SPACE

The objective of this method is to attract the termite workers to forage on a slow-acting insect- growth regulator (IGR) called hexaflumuron that will work to eliminate the termite workers population and eventually result in the death of the queen and any subsequent future queens, and therefore the entire colony.

COLONY ELIMINATION

course is a filter layer of finer material that is installed over a coarse road base material. The purpose of the choker course is to provide a stable foundation of fine-grained aggregate for the construction of a pavement.

CHOKER

SUBGRADE AND BASE COURSE MATERIALS

BARROW MATERIALS BASE COURSE MATERIALS CHOKER AGGREGATE

a dark brown to black cementitious material, solid or semi-solid, composed of bitumens which when mixed with graded aggregates is used as paving material by placing, shaping, and compacting while hot over a prepared base.

ASPHALTIC CONCRETE

paving for roads and other surfaces formed by grading and compacting layers of crushed stone or gravel, then the top layer is bound by asphalt to stabilize the stone,
