FERROCEMENT BOATS SAMSON MARINE & HARTLEY AND BROOKS HAVE BOAT CONSTRUCTION PLANS WOODEN BATTEN TO SHAPE HULL FORM CONSTRUCTION: 3 COATS OF GALVANIZED CHICKEN WIRE TO COVER ALL HULL, WITH FISH NET BEHIND METAL RODS(WIRE MESH) WIRE TYEING DEVICE (FOR THE ABOVE MATERIAL): INSTALL (WELD) A 1/4" DIAMETER ROD TO THE VICEGRIPS TO INSERT INTO THE HAND DRILL AND USE AS A TYEING TOOL MORTAR SAND+ WATER WITH INHIBITOR ON THE WATER TO STOP CORROSION OF METAL Before you cement the hull, install all your ports(holes) for bilges, holding tanks,clits, anchor settings, etc. all with stainless steel. On the basis of a material – anodes are Zinc anodes and aluminium, anodes are preferred in the marine industry. In the case of a ship, seawater acts as an electrolyte and transfers the electrons from the anode by oxidizing it over the steel plate and making a protecting layer The anode will corrode first sacrificing itself for the o...

EPOXY PROCEDURES (II)

EPOXY PROCEDURES ( WINKYPEDIA ) Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and is capable of restoring the concrete to its pre-cracked strength. Prior to doing any injection it is necessary to determine the cause of the crack. If the source of cracking has not been determined and remedied, the concrete may crack again. (VERIFY WITH MOHR’S CIRCLE, (esfuerzos principales perpendiculars al esfuerzo principal) Materials • CI-LV and CI-SLV for repair of hairline cracks (0.002") and those up to 1⁄4" in width. • CI-LV FS and CI-LPL for repair of fine to medium-width cracks (suggested width range: 1/64"–1⁄4 • CI-GV for repair of medium-width cracks (suggested width range: 3⁄32"–1⁄4"). • Crack-Pac® injection epoxy for repair of fine to medium non-structural cracks (suggested width range: 1/64"–1⁄4 • Crack-Pac Flex-H2O polyurethane crack sealer for repair of fine- to medium-width cracks (sugge...

CONCRETE EPOXY INJECTION (I)

EPOXY THE EPOXY INJECTION OF CONCRETE IS TO PROVIDE CONTINUITY ON THE CONCRETE. FOR STRUCTURAL CRACKS REFER TO THE MOHR’S THEOREM, IN WHICH THE REPAIRS OF THE CONCRETE HAVE TO BE PERPENDICULAR TO THE CRACK, DO TO THE PRINCIPAL STRESS. 220V high pressure grouting machine epoxy injection $279.00 (ebay) Grouting Machine Electric Epoxy Injection Piston Pump Leakage Plugging Rico AC Grouting Machine Electric Epoxy Injection Piston Pump Leakage Plugging Rico AC US $489.02 EPOXY ACCESSORIES EPOXY MACHINE GAUGE EPOXY PORTS DESCRIPTION: Applied Technologies # AT-DCN24795 Concrete Crack Injection port, design allows port to be adhesively mounted on concrete foundation wall and crack injection materials to be injected into the cracks. Attach to concrete crack surface using surface sealer epoxy paste (Not Supplied). After using, cap fits tightly and stops concrete crack injection material from flowing out.
